Abstract
An apparatus or device for collecting aerosol particles from a gas stream, having a collector body enclosing a collector channel, a particle trap in the collector channel, and an injection duct for injecting a discrete microdroplet of an elution reagent. The particle trap may be a centrifugal impactor, a bluff body impactor, or an electrostatic impactor. Aerosol particles are deposited on the surface during collection and are subsequently eluted with a microdroplet or a series of microdroplets as a concentrated liquid sample so that the sample can be analyzed in situ or conveyed to a detector for analysis. The collector serves as an aerosol-to-liquid conversion module as part of an apparatus for detecting and analyzing aerosol particles, and may be used in an integrated environmental threat assessment system, for example for characterization of aerosolized chemical and biological weapons, or for industrial or environmental monitoring.
